empty JTable

[Vijay]

I have a JTable whose values gets filled only dynamically.
At times, when the table is empty, I want to show a message like
"no records found" just under the table header.
Just like how in windows machine, when you make a search and if it doesnt
return any records, it prints "Search is complete. There are no results to display"
(stretching many columns) under the table header. I considered using JLabel
(as shown below) but there is always some space b/w the two components.
Let me know ur suggestions. Until then, lemme try out other Layout managers.
Just a code snippet:

class MyTable extends JFrame {
    private JPanel topPanel;
    private JTable table;
    private JScrollPane scrollPane;
    
    public MyTable() {
        setSize( 300, 150 );
        topPanel = new JPanel();
        topPanel.setLayout( new BorderLayout() );
        getContentPane().add( topPanel );
        String columnNames[] = { "Column 1", "Column 2", "Column 3" };
        String dataValues[][] = {};
        table = new JTable( dataValues, columnNames );
        scrollPane = new JScrollPane( table );
        topPanel.add( scrollPane, BorderLayout.CENTER );
        topPanel.add(new Label("No records available"),BorderLayout.SOUTH);
    }
    
    public static void main( String args[] ) {
        MyTable t = new MyTable();
        t.setVisible( true );
    }
}

First, I suggest you to use a TableModel (e.g. AbstractTableModel) to separate data from the GUI.

You can temporarily add the label to the table:

//topPanel.add(new Label("No records available"),BorderLayout.SOUTH);
JLabel label = new JLabel("No records available");
label.setSize( label.getPreferredSize() );
table.add(label);
table.setFillsViewportHeight(true);

Then when you start adding data to the table you would need to remove the label from the table.
